Strengths of TCP/IP protocol i. This protocol is interoperable allowing the communication between heterogeneous networks through a cross platform layer. ii. The protocol is scalable allowing the addition of networks to the existing one without interrupting the current operations iii. It is able to uniquely identify nodes and other devices in the network as it uniquely assigns each computer its IP address Weaknesses of TCP/IP protocol i. This protocol isn’t generic in its nature. It cannot represent any other protocol stack except the TCP/IP suite. ii. It is very difficult to differentiate between physical layer and data link layer. Proper protocols should differentiate the two layers iii. Differentiating between services, protocols and interfaces thus it is not suitable for a latest technologies to new networks
